Reuters (4/2) reports that according to a study published March 31 in the journal Circulation, young adults who do not have hypertension or higher than normal blood pressure may maintain better cognitive function in their middle years, compared to young adults whose blood pressure was higher than normal. For the study, researchers followed more than 3,000 young adults ranging in age from 18 to 30 for 25 years. At the 25-year point, participants underwent a battery of tests to evaluate various cognitive functions.
